Having thus described my invention what Letters Patent, is:

1. In a device of the character specified, the combination with the valve casing, of a plug provided with an oil reservoir, a valve ort through the plug registering with ports in the casing to form a passageway through the valve, and means to feed a measured charge of oil from the reservoir to the passageway each time the valve is closed and open (1 e 2.
